To the Editor:—  We read with interest the article of Conzen et al.  1 demonstrating a reduction of cardiac troponin I release after coronary artery bypass grafting on the beating heart when sevoflurane was compared to propofol. Most previous studies identified peak postoperative troponin I as the major endpoint. 2,3 It is not clear from the article of Conzen et al.  which was the peak postoperative troponin I value in the two groups and whether this value was significantly different.
